To be fair, O2 has a massive issue with scammers and they need to do something about it. I switched to O2 about a year ago, keeping my old number. I’d rarely get scam calls or texts before I switched but since I’ve been with o2, I get 5-10 calls a week. Particularly annoying because I have to answer my phone due to my job

How does that work out in terms of energy consumption though?

If NVMe is at least 10x faster, but consumes 5x more power, it will use less energy to read or write the same amount of data overall.

Agreed about the data farming, but I would recommend reading this if you haven’t already. Not properly implementing the conventions is basically step 1 in that article.
